Example Embodiment

[0010] The specific embodiments of the present invention will be further described in detail below with reference to the examples. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0011] A PVC external lubricant according to a preferred embodiment of the present invention includes the following components by mass percentage: octadecanoic acid 55%, dibutyl phthalate 38.5%, phosphoric acid 0.5%, white oil 1%, higher fatty acid barium 5%.

[0012] The components of the lubricant are added with metal soap: barium higher fatty acid, which not only has a lubricating effect, but also improves its thermal stability. The lubricant has good lubricity and dispersibility, ensures the plasticizing effect, and improves the Productivity.

Abstract

The invention relates to the field of plastic processing and especially relates to a PVC external lubricant. The PVC external lubricant comprises, by mass, 55% of stearic acid, 38.5% of dibutyl phthalate, 0.5% of phosphoric acid, 1% of white oil and 5% of higher fatty acid barium salt. The PVC external lubricant has excellent lubrication performances, uses a stabilizing agent component and has better thermostability.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a PVC external lubricant. Background technique [0002] PVC resin is formed by free radical polymerization of vinyl chloride. PVC resin can be processed into various plastic products, widely used in various films, coating products, foam products and so on. With the development of my country's economy, the scale of PVC products industry is constantly expanding, and the output is increasing year by year. [0003] During the PVC molding process, there is interface friction between PVC and the mechanical surface of the processing equipment, and an external lubricant needs to be added to reduce the friction. The external lubricant has little compatibility with the polymer, and it is easy to transfer from the interior of the polymer to the surface during processing, forming a lubricant molecular layer at the interface. Due to the low cohesive energy of the lubricant, it can reduce t...
